I'm not too sold on landfall as a build around. From my experience playing boros bushwacker in standard, the deck had this akward problem of needing to draw both gas and a land to keep going. I can probably mitigate that by making the fetchland case worse and the no land drop case better, but I'm not sure that solves the problem of how people feel, even if the gameplay is fine.
On topic:
I've been looking at white cards, looking for cool ones I could use/improve on. I'm only at the 4 drops so far, but I've still found a few cool cards:
Battallion is interesting. I've noticed that white's 3 power creatures
either tend to be fragile or
cost 4, most of their creatures don't punch above their CMC, they're evasive or have utility instead. Maybe batallion is an interesting way to fill that gap?
Ever the interesting card. Would it be too good if it afected all your creatures?
Might be an interesting savannah lion
Interesting, but unfortunatly bad. I love me some spellskite though, maybe there's a happy medium?
I've got a casual deck with this + the enchantment creatures from theros. Maybe that's worth cubing?
If double strike turns into heroic, this could be interesting. I might make a new version though, I don't like protection, even like this.
Maybe worth revisiting with prowess? Never did enough beforehand
I'd love if this guy was workable. Maybe he should be?
I miss this guy
Enchantment avoids people regrowing bolts while still supporting prowess. I'd be removing the tap symbol like FSR does though
I almost love this creature, it might need a better body
If you do want landfall, this card could be interesting
This is a card I'd love to have in my cube somehow.
Something like this could be an interesting disruptive creature
Good enough if it cost 1?
